Required logarithmic function is :

[tex]f\left(x\right)=\log_3\left(x\right)[/tex]

Step-by-step explanation:

We have been fiven that table for the logarithmic function is:

x f(x)

9 2

27 3

81 4

which can be rewritten as:

x f(x)

3^2 2

3^3 3

3^4 4

Which are basically powers of 3

So we can use logarithmic function as

[tex]\log_3\left(9\right)=\log_3\left(3^2\right)=2\log_3\left(3\right)=2(1)=2[/tex]

Hence required logarithmic function is :

[tex]f\left(x\right)=\log_3\left(x\right)[/tex]

Answer:

85%

Step-by-step explanation:

If the sporting goods store received a lot of 80 baseball caps... and 12 of them were green that means that 68 (80-12) were NOT green.

Thus, the probably to randomly pick up a cap that is NOT green is 68 out of 80...

68/80 = 17/20 = 85%

The answer is:

The correct option is:

B)  [tex]5^{12}\div5^{4}=5^{8}[/tex]

To solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

[tex]\frac{a^{m} }{a^{n} }=a^{m-n}[/tex]

If we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

So, we are given the expression:

[tex]5^{12}\div5^{4}[/tex]

Which is equal to write:

[tex]\frac{5^{12} }{5^{4}}[/tex]

Then, calculating we have:

[tex]\frac{5^{12} }{5^{4}}=5^{12-4}=5^{8}[/tex]

Hence, the answer is:

B)  [tex]\frac{5^{12} }{5^{4}}=5^{8}[/tex]

or

 [tex]5^{12}\div5^{4}=5^{8}[/tex]

For this case we must find the product of the following expression:[tex]3 (x + 4) (x-5)[/tex]

We must apply distributive property to the terms of the first parenthesis:

[tex](3x + 12) (x-5) =[/tex]

Again we apply the distributive property:

[tex]3x ^ 2-15x + 12x-60 =\\3x ^ 2-3x-60[/tex]

ANswer:

[tex]3x ^ 2-3x-60[/tex]

Step 1: Distribute the 3 to x and 4

(3x + 12)(x - 5)

Step 2: FOIL (First, Outside, Inside, Last)

Multiply the first of the values in the parentheses together

(3x + 12) (x - 5)

[tex]3x^{2}[/tex]

Multiply the outside values in the parentheses together

(3x + 12)(x - 5)

-15x

Multiply the inside values of the parentheses together

(3x + 12)(x - 5)

12x

Multiply the last values of the parentheses together

(3x + 12)(x - 5)

-60

Step 3: Add all the FOIL values together

3[tex]x^{2}[/tex] + (-15x) + 12x + (-60)

Step 4: Combine like terms

3[tex]x^{2}[/tex] + (-15x) + 12x + (-60)

3[tex]x^{2}[/tex] - 3x - 60

Answer:

D. f(2) = 0

Step-by-step explanation:

If x-2 is a factor of a function, then f(2) must be zero

f(x) = p(x) * (x-2) since (x-2) is a factor of f(x)

Substitute in x=2

f(2) = p(2) (2-2)

f(2) = p(2) *(0)

Anything times 0 = 0

f(2) = 0

Final answer:

To determine the number of dimes Jared has, we set up an equation based on the total value of dimes and quarters equaling $5.50. After solving the equation, we find that Jared has 10 dimes.

Explanation:

The student's question asks how many dimes Jared has if he has a total of $5.50 consisting of quarters and dimes, with 8 more quarters than dimes. Let 'd' represent the number of dimes. Since a dime is worth $0.10, the total value of the dimes is 0.10d dollars. Jared has 8 more quarters than dimes, so he has 'd+8' quarters. A quarter is worth $0.25, so the total value of the quarters is 0.25(d+8). The sum of the values of the dimes and quarters is $5.50, so we can set up the equation 0.10d + 0.25(d+8) = 5.50.

Now, solving for d:

0.10d + 0.25(d+8) = 5.50

0.10d + 0.25d + 2 = 5.50

0.35d + 2 = 5.50

0.35d = 5.50 - 2

0.35d = 3.50

d = 3.50 / 0.35

d = 10

Jared has 10 dimes.

The correct choices are:

[tex] {8a}^{15} - 27[/tex]

and

[tex]216 {a}^{6} - 27 {y}^{3} [/tex]

EXPLANATION

A difference of perfect cube is of the form:

[tex] {(m)}^{3} - {(n)}^{3} [/tex]

We can rewrite

[tex]216 {a}^{6} - 27 {y}^{3} [/tex]

Try rewriting the terms as powers to an exponent of 3.

[tex]216 {a}^{6} - 27 {y}^{3} = {6}^{3}( {a}^{2})^{3} - {3}^{3} {y}^{3} [/tex]

This implies that:

[tex]216 {a}^{6} - 27 {y}^{3} = ( 6 {a}^{2})^{3} - {(3y)}^{3} [/tex]

Hence this is a difference of perfect cube.

Also, we can rewrite

[tex] {8a}^{15} - 27[/tex]

as

[tex]{8a}^{15} - 27 = {2}^{3} ( {a}^{5})^{3} - {3}^{3} [/tex]

[tex]{8a}^{15} - 27= {(2{a}^{5})}^{3} - {3}^{3} [/tex]

The Riemann sum for f(x) = 2x on [2,4] is evaluated as n approaches infinity to give the integral from 2 to 4 of 2x dx, resulting in an area of 12 square units under the curve.

To find the Riemann sum for the function f(x) = 2x over the interval [2, 4], we start by dividing the interval into n equal subintervals, with each subinterval of width ∆x = (b - a) / n. For the right-hand endpoint, the kth point c at which f(x) is evaluated is given by c_k = a + k*∆x. Therefore, the Riemann sum is:

∑_{k=1}^{n}f(c_k)*∆x = ∑_{k=1}^{n}2(a + k*∆x)*∆x.

As n → ∞, the Riemann sum approaches the definite integral of the function. For the given function, the integral can be calculated directly, and the limit of the Riemann sum as n approaches infinity gives us the area under the curve, which in this case is equivalent to the area of a right triangle with base 2 and height 4.

Thus, we find that the area under the curve on the interval [2, 4] for f(x) = 2x is simply integral from 2 to 4 of 2x dx, which evaluates to 4^2 - 2^2, or 12 square units.

Step-by-step explanation:

Use the formula for the SA of a hemisphere.

[tex]SA=2\pi r^2[/tex]

Now we can find the radius of the hemisphere, which is 15.

Then, we can square that and multiply it by 2 to get 450.

Now, let's use the formula for the Volume of a hemisphere.

[tex]V=\frac{2\pi r^3}{3}[/tex]

Now we can cube 15 and multiply it by 2 to get 6750.

Then we can divide this number by 3.

The question is asking to solve a problem that'll "add up", or in other words, makes sense; through the use of Trigonometric functions. The leaning ladder is the hypotenuse of 17ft, adjacent to that is a wall that measures 16.5ft above the ground. The angle both sides make must be <=70°. The function here is Opposite over Hypotenuse i.e 16.5/17 . We use the inverse operation of Sin which is Sin^(-1) to find if the angle is < or = to 70°. Using a calculator, we find the angle to be 76.06°, which is > more than, 70°.

Thus, the ladder will not be safe for its height and therefore won't make sense.

Answer:

  f(x)

Step-by-step explanation:

f(x) apparently has an initial value of 15.

g(x) apparently will have an initial value of 6 or less, since g(1) = 6 and it has increasing slope.

h(0) = 4^0 +3 = 3

j(0) = 10·2^0 = 10

The largest initial value among the initial values {15, <6, 3, 10} is 15.

  f(x) has the largest y-intercept

_____

The graph shows two ways g(x) can be modeled. One is exponential with an initial value of 4; the other is quadratic with an initial value of 6.

Final answer:

Among the functions provided, j(x) = 10(2)^x has the highest y-intercept, which is 10, found by evaluating the function at x equals 0.

Explanation:

To determine which function has the highest y-intercept, we need to examine each function and look for the point where the graph crosses the y-axis (when x is 0). Unfortunately, the only function provided with enough information to determine the y-intercept directly is h(x) = 4^x + 3. Evaluating h at x equals 0 gives us h(0) = 4^0 + 3, which simplifies to 1 + 3, yielding a y-intercept of 4. The function j(x) = 10(2)^x would have a y-intercept of 10 when x is 0. However, without the specifics of f(x) and not enough points to determine a pattern in g(x), it is not possible to accurately determine their y-intercepts. Thus, between h(x) and j(x), j(x) has the highest y-intercept at 10.

Answer:

C = 26.5g - 2

Step-by-step explanation:

We can plug in our given numbers for g and see if the C corresponds.

g = 7, C = 16.55

A) C = 2.65*7 --> C = 18.55

We know that C ≠ 18.55, so it should be B (I think you typed that one wrong, it is C = 2.65g - 2)

The equation C=2.65g could be used to determine the cost for purchasing g gallons of gasoline with the discount.

To determine the cost for purchasing g gallons of gasoline with the discount, we need to examine the given options. Option A states that the cost, C, equals 2.65g, which means the cost is directly proportional to the number of gallons. This could be a valid equation for determining the cost with the discount. However, option B states that the cost, C, equals 2.65g-12. This equation subtracts a constant value of 12, which is not mentioned in the problem, so it is not a valid way to determine the cost with the discount. Therefore, option A could be used to determine the cost for purchasing g gallons of gasoline with the discount.

The population of the village today is 720 people.

To find the population of the village today, we need to calculate the number of population doublings that have occurred over the four hundred year period.

Since the population triples every one hundred years, it doubles twice in that time frame.

Doubling a number is the same as multiplying it by 2.

So, the population at the start was 20, then it doubled to 40 after one hundred years, and doubled again to 80 after two hundred years.

Finally, it tripled to 240 after three hundred years, and tripled again to 720 after four hundred years.

Step-by-step explanation:

From the circumference we need to find the radius.

Since C = 2*pi*r, r = C / (2*pi).

Here, with C = 25  1/7 in, r = (25  1/7 in) / [ 2(22/7) ], or r = 4 in

Given that Peter contributes 20% of the total money and his part is $4.00, it is deduced that the total combined amount the five brothers have is $20.00.

To solve this, we can set up a simple proportion where 20% (or 0.20 in decimal form) of the total amount is equal to $4.00.

Step-by-Step Solution:

Let x represent the total combined amount of money that Peter and his brothers have.

Since Peter contributes 20% of the total, we can express this as 0.20 imes x = $4.00.

To find x, we divide both sides of the equation by 0.20, giving us x = $4.00 / 0.20.

By performing the division, we find that x = $20.00.

Therefore, the total combined amount Peter and his brothers have is $20.00.

Answer: r=16tan theta sec theta

Step-by-step explanation:

I have this question on my test but all the answers are different except that one

The polar form of the parametric equation is option (A), r = 16 tan theta sec theta is the correct answer.

Polar form of a complex number is represented by a line whose length is the amplitude and by the phase angle. A polar form of a vector is denoted by  ( , ) , where represents the distance from the origin and represents the angle measured from the -axis.

Given the parametric equations x=4t and y=t².

Consider x= 4t

⇒ t = x/4

Now substitute  t in y equation,

[tex]y= (\frac{x}{4} )^2[/tex]

[tex]y=\frac{x^2}{16}[/tex]

We know that in polar form,

x= r cosθ and y= r sinθ

Now y becomes

r sinθ= [tex]\frac{r^2\cos^2\theta}{16}[/tex]

16 r sin θ = r² cos²θ

r = 16 sinθ/cos²θ

⇒r =16 tanθ secθ

Hence we can conclude that the polar form of the parametric equation is option (A), r = 16 tan theta sec theta is the correct answer.
